Unity ScrollViewScope horizontal scroll not working with EditorGUILayout

Question

I need to use EditorGUI.IndentLevelScope and it only work with EditorGUILayout like LabelField, Foldout, not in GUILayout like Label.

here is my code

                using (var midScroll = new EditorGUILayout.ScrollViewScope(midSPos, true, true))
                {
                    using (new EditorGUI.IndentLevelScope(1))
                    {
                        midSPos = midScroll.scrollPosition;
                        for (int i = 0; i < 50; i++)
                        {
                            EditorGUILayout.LabelField("This is a EditorGUILayout.LabelField. This is a EditorGUILayout.LabelField.", GUI.skin.GetStyle("LinkLabel"));
                        }
                    }

same code with GUILayout.Label work both what do i miss

Answer 1

End up I found a solution for Label by adding an empty PrefixLabel in front and back to GUILayout again, the scroll now works.

HorizontalScope
    EditorGUILayout.PrefixLabel("");
    GUILayout.Label("content");

But still, have some issues with my foldout like this since I can't add HorizontalScope to it.

InitRow(row row)
{
    if (isShowing = EditorGUILayout.Foldout(isShowing, "Foldout"))
    {
        InitRow(child);
    }
}
